Mobile ad hoc networks (MANET) are characterized by frequent node mobility and multi-hop wireless links without infrastructure. We present an AODV-based routing algorithm, Ad-hoc On-demand Distance Vector with IntrAzone Routing Protocol (AODV-IARP), for mobile ad hoc networks. AODV-IARP is a global position-less flat hybrid routing protocol. In this protocol, each node see the network as two zones, intrazone and interzone. It periodically broadcasts hello message with its neighbors. A node can learn the routes to nodes two hops away by receiving hello message. This procedure maintains routing through a proactive component called the IntrAzone Routing Protocol (IARP). The IntErzone Routing Protocol (IERP) is responsible for acquiring routes that are not located in intrazone. The IERP uses AODV to discover destination on demand. Our simulation shows that AODV-IARP, compared to AODV, incurs less delay and less control traffic with large density of nodes. We also obtain AODV-IARP’s optimal length of hello interval for different node mobility.
